I'm currently trying to template the TrackBallInfo popup and in doing so I hoped to be able to use the behavior's "TrackInfoUpdated" event.

This is the XAML:


... and here's the code behing event handler ...


When I build this I get this errors from the compiler:


The first two are quite surprising. So far as I've seen they only show up when I try using this event. The third error is just weird. I checked and double checked and the method seem to fully comply with the expected event handler signature. 

Any assistance would be greatly appreciated!

How do you use drag and drop to reorder tasks in a GanttView?

Hi,

I have bind the radgrid with its datasource as a dataset.This dataset contains four tables and relations are also specified in it.So a heirachy is being created in grid,now I want to remove the headers of all the grids in heirarchy but want to keep the header of main Parent grid at top only .

Can you please help?

Thanks in Advance..

Hi there

I am currently using the RadGridView to display periodic data with the date in the column header and the value in the cells

see AdornerIssueImage1.png

The ItemsSource for the Grid is bound to a collection of view model objects that are made up of set values (Group and Category) and a collection of values.  The number of values can vary so the columns for the grid are actually set up in the code behind rather than being declaratively defined in the XAML.

Each cell can have a comment associated with it which is represented by a red triangle in the top left corner of the cell. To achieve this  a custom StyleSelector has been created that is assigned to the column CellStyleSelector. In the SelectStyle method a custom adorner is added to the AdornerLayer of the GridViewCell if a comment has been added. (annoyingly the SelectStyle method has to be manually called to get this happen, but that's another discussion).

see AdornerIssueImage2.png

The issue I am having is that if the rows are grouped, and there are comments applied to some of the top rows, and the group is then collapsed then the comment adorner shows in the group header of the group beneath the collapsed group.

see AdornerIssueImage3.png

Do you have any suggestions/thoughts/work arounds on this issue? or do you have a preferred way of generating the same UI.

Any help would be appreciated.

Cheers
                                                                                                    

How can I do to control if a connection can be attached to a connector according to its underlying graphsource model ?

If I noticed that we can take profit from ConnectionManipulationStarted and ConnectionManipulationCompleted events to act on floating connection, I have yet many doubts. 

- ConnectionManipulationStarted provides way to control the creation of a connection from a connector (Take into account the multiplicity defined by the underlying graphsource model ...).

- ConnectionManipulationCompleted
provides way to act on the result of the manipulation. So, for example, if a diagram doesn't allow connection when target shape is null, you can remove it on this event.
It's a shame that the ConnectionUtilities.DeactivateConnectors is not a public method.

That being said, these events don't provide mechanism to act before that the connectors on target shape are activated. I like to go to another visual state if the target connector should not be used by the connection.
ConnectionUtilities lists method such as IsTargetShapeValid or  ActivateNearestConnector.
Are there any ways to intercept these calls and monitor connector activation ?

Developing my own connector, I can override the UpdateVisualStates method, but I don't have much information to do something interesting.
And MouseMove... methods are not always called.

Is there another way to follow to achieve this?

Hi

I am playing with mindmap sample provided with Q2 2012 release and I am trying to display the connectors handles around the mindmap shapes. I tough that I would only had to add the corresponding VisualState as well as the ConnectorsControl on the shape template to get the connection adorner to display the connector anchors around the shapes but I can't get the diagram to show them when I hover a shape with a connection start.

Here is the visual state  I added as well as the corresponding ConnectorsControl I added to the mindmap shape template:
<VisualStateGroup x:Name="ConnectorsAdornerVisibilityStates">
         <VisualState x:Name="ConnectorsAdornerCollapsed"/>
         <VisualState x:Name="ConnectorsAdornerVisible">
          <Storyboard>
           <ObjectAnimationUsingKeyFrames Duration="0" Storyboard.TargetProperty="Visibility" Storyboard.TargetName="ConnectorsControl">
            <DiscreteObjectKeyFrame KeyTime="0">
             <DiscreteObjectKeyFrame.Value>
              <Visibility>Visible</Visibility>
             </DiscreteObjectKeyFrame.Value>
            </DiscreteObjectKeyFrame>
           </ObjectAnimationUsingKeyFrames>
          </Storyboard>
         </VisualState>
        </VisualStateGroup>
...
<Telerik_Windows_Controls_Diagrams_Primitives:ConnectorsControl x:Name="ConnectorsControl" ItemContainerStyle="{TemplateBinding ConnectorStyle}" Visibility="Visible"/>

Anyone could share a pointer on how to display those connectors on the mindmap shapes?

Hello,

Last week I converted from 2011Q3  Scheduler to the 2012Q1 ScheduleView

I got all of my custom code to work again, but I am running into 1 problem
Resizing (no custom code) does not work properly any more I am using a custom appointment.
Moving a appointment does work all the time

I get the following error 

Hello, 

i have a gridview with auto generated Colums.
After i reorded columns i cant reload gridview from stream(i see only empty Gridview ). See attched Screenshot

i am working with version 2010.3.1110.35
i have this in the listbox itemTemplate

<

 

telerik:RadComboBox x:Name="FieldComboBox" Grid.Column="0" ItemsSource="{Binding Fields}" SelectedItem="{Binding Field,UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" />

 

 

Field returns a class that implements

INotifyPropertyChanged

and Fields returns a List<Field>



now when i ran the application, if i set a breakpoint on get field, i can see it is trying to get it,
and that the value returned is correct

but when gui is finished loading

selectedindex is set to -1 and selecteditem and selectedvalue is set to null , and combobox doesn't show the selection of the field


but if i change the line into

<ComboBox x:Name="FieldComboBox" Grid.Column="0" ItemsSource="{Binding Fields}" SelectedItem="{Binding Field,UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" />

and use the regular wpf combobox it will work


it only happens when it's loaded , after it's loaded if i change stuff , it will work , but the first time doesn't work


how can i solved this?

thanks

Hi

I've just downloaded Q1 2012 SP1, and note that there are two folders - one the usual Binaries - Wpf35/Wpf40 and another one called Binaries.NoXaml.

What's the difference between the binaries in each of these folders?

I always copy the binaries over to the lib folder in my application and check them into source control.

I am running VS Beta 11 + Net 4.5 in a Virtual PC. Just running an already compiled application that was complied on a PC without VS Beta 11, is giving me some very strange errors in RadComboBoxes - basically something bound to SelectedValue/SelectedValuePath always returns null for SelectedValue.


where ItemsSource is a collection of 

and EntityToInsert is a simple get;set; property defined in the ViewModel.



If I run the same app on a machine without VS Beta 11 installed I have no problems whatsoever. I was hoping that Q1 2012 SP1 would address this, but alas not. 

I noticed that prior to installing the internal build 2012.1.319 on the Virtual machine - the sizing of all Telerik RadControls was all over the place. 2012.1.319 fixed all the sizing issues but not the question of the SelectedValue.

I would love to run VS Beta 11 on my main machine, but dare not install it since it is obviously breaking some of your controls.

I've attached two screen shots of Snoop looking at the form. In VS2010 the SelectedValue is correct, while in VS2011 it is null. This is exactly the same code base.
